Last night, during her final debate with Jim Graves, moderator Tom Hauser gave Bachmann an opportunity to backtrack. But instead of trying to qualify her accusation, she implied that the September attack on the U.S. consulate in Benghazi actually validated her concerns.

Here's a transcript of the exchange, followed by the video:

BACHMANN: These are five letters [laying out our Muslim Brotherhood concerns] that we sent to the Inspectors General, myself and five other colleagues. I certainly do stand by those letters, because what we know is that terrorism continues to remain a very real threat in the U.S. I serve on the Intelligence Committee. We deal with the classified secrets of the nation. We have a number of people who came out in support of us.

The events in Benghazi have proved that the United States remains under attack both in the Middle East and here in the United States.

HAUSER: But there has been no proof the Muslim Brotherhood was involved in Benghazi, has there?

BACHMANN: We are only beginning on what-- Ansar al-Sharia has claimed responsibility in Benghazi, again, the Muslim Brotherhood is a violent organization and there is a spillover effect between these various violent militia groups.

HAUSER [speaking to Graves]: At the time you called these accusation ridiculous and outrageous...

GRAVES: They are, they are inflammatory, and I'll stand with Senator Mccain and [Speaker] Boehner and with Lindsay Graham on that, okay. But here's the thing -- there is nothing more important in the country than to protect the people, and I stand by that 100 percent. But we don't need to polarize, we don't need to antagonize, we don't need to throw mud especially when it's not even called for...

BACHMANN: That's exactly why, thank God, we have members of Congress that are asking questions. That's all we did.

HAUSER: But you went beyond raising questions. You made an accusation about the Muslim Brotherhood.

BACHMANN: No we did not make an accusation, we asked questions. We asked the Inspectors General to take a look. It certainly is within reason to think these violent organizations who have declared almost on a weekly basis they want the destruction of Israel and the United States -- when madmen speak, listen and pay attention. That was the problem with the Obama administration -- they didn't listen, they didn't pay attention, and a tragedy ensued, we need members of Congress who will ask the tough questions, and we did.

So now Bachmann says she was never making accusations? Here, to refresh your memory, is what she said back in July: "It appears that there has been deep penetration in the halls of our United States government by the Muslim Brotherhood... that there are individuals who are associated with the Muslim Brotherhood who have positions, very sensitive positions, in our Department of Justice, our Department of Homeland Security, potentially even in the National Intelligence Agency."
